Permit to Discharge
What is a permit?
If you can not comply with the exemption criteria, you will need to apply to the Environment Agency for a permit. A permit is a way of obtaining permission to discharge sewage effluent. There are two types of permit; the standard rules permit and the bespoke permit.
Obtaining a permit
If you are discharging to surface water, check that you can comply with the standard rules for the standard rules permit. If not you will need to apply for a bespoke permit. If you are discharging to groundwater, check with the Environment Agency to see which permit will apply.
The Standard Rules
Apply for a standard permit if you can meet the following criteria:
* The discharge must be domestic and not contain any trade effluent
* It must be impractical to connect to a foul sewer
* The sewage treatment plant must be designed and built to BS 12566 and sized according to Flows and Loads 3
* The treatment plant is operated and maintained according to the Manufacturer’s recommendations
* The discharge is made into a watercourse (and normally contains water throughout the year)
* The discharge cannot be made to water that is 1km upstream of an identified bathing water, a designated shellfish water, European Site , Ramsar site, Site of Special Scientific Interest (SSSI), National Nature Reserve, Local Nature Reserve or any body of water identified as containing a Protected Species or within 100m from a Local Wildlife site. This restriction only applies to conservation sites that are water-based and linked to the receiving water downstream of the discharge point.

If you cannot meet the criteria above, you will need to apply for a bespoke permit. The application should include information on which criteria cannot be filled.
